Oh, okay. Thank you. I hadn't understood “companies”.
You look at the qualifying expenditure or qualifying activities related to acquiring a patent or other forms of intellectual property, your investment in building know-how, which in agricultural markets probably should include trade secrets. That establishes the expenditure base as a share of your total expenditures.
Then you look at the income that's derived from the activity associated with the intellectual property—in other words, royalties you subsequently earn through exploiting the IP that you have developed, created, or purchased. That portion of your income would be taxed at a lower rate than the general corporate income tax rate. A typical ratio would be that the preferred rate—the patent box or the innovation box rate—would be half of the general corporate rate.
